Abstract

PROBLEM TO BE SOLVED: To solve the problem of conventional crime prevention measures only having suspicious persons intruding from outside a facility as subject but on the other hand, the fact that the person activating the crime prevention device and the crime prevention system is a party of the facility and especially that the person starting the crime prevention device and leaving the facility last is in a very important position in crime prevention management has not been focused on.SOLUTION: A crime prevention device having: a crime prevention operating unit for having a crime prevention function operate; a control unit for controlling the crime prevention operating unit; an operator imaging unit for imaging an operator when an operation to the control unit occurs; and a record retaining unit for retaining a record of the operator imaging unit is proposed.

Description

  The present invention relates to a security device and a building structure that can use the security device and has a locking device at an entrance.

  In various facilities such as commercial facilities and offices where business hours and working hours are determined, if the business hours are out of business hours or out of business hours (mainly at night), there are basically no people left from the facilities. For this reason, technologies related to various crime prevention devices or crime prevention systems have been disclosed for the purpose of preventing intruders from entering the facility during the time period.

  Many of them employ a configuration in which various sensors are used to detect intrusion by a suspicious person in the facility before or after the event and issue an alarm. Specifically, Patent Document 1 discloses a technique related to a crime prevention device that not only detects an intruder by a sensor but issues an alarm, but also records the physical characteristics of the intruder. This crime prevention device has a function not to send an alarm when it is determined that the recorded physical characteristics of the intruder are the same person as the person having the physical characteristics registered in advance. It is characterized by the fact that it acts so as not to send alarms unnecessarily to the entry and exit of householders and staff of the facility.

JP 2004-348407 A

  Here, in the conventional crime prevention device or crime prevention system, the target of the crime prevention measure is a suspicious person who enters from outside the facility. However, it is the person concerned with the facility who operates the security device and the security system, and especially that the person who activates the security device and leaves the facility at the end is in an important position for security management of the facility. Not much attention has been paid. Specifically, the person who leaves the facility at the end is in a position to lock the facility, and if an accident or incident occurs in a facility where no one is present, The significance of identifying the person who left the facility last is not small in understanding and analyzing the responsibility.

  Here, as an example of the fact that the prior art is not interested in identifying the facility staff who finally leaves, Patent Document 1 is cited. This document discloses a technology related to a crime prevention device that does not sound an alarm even if it detects the presence of a person whose physical features have been registered in advance. In the unlikely event that a person involved in the facility commits a crime such as theft in the facility, the physical characteristics of the person who has committed the crime are registered in advance because the person is involved in the facility. Because of the same characteristics as the above, a situation in which an alarm or the like is not generated occurs, and the body as a security device is not made.

  In order to avoid the above situation and to add a new function not found in the conventional crime prevention device, the present invention includes a crime prevention operation unit for operating the crime prevention function, a control unit for controlling the crime prevention operation unit, A crime prevention device having an operator photographing unit for photographing an operator when an operation is performed on a control unit, and a record holding unit for holding a record of the operator photographing unit is proposed.

  According to the present invention having the above-described configuration, it is possible to construct a strong crime prevention measure in the facility.

<< Embodiment 1 >>
<Overview>
FIG. 1 is a conceptual diagram for explaining an example of implementation of the crime prevention device of the present embodiment. As shown in this figure, the “security device” 0101 according to the present embodiment not only operates the crime prevention function but also shoots and records the operator when the operator performs an operation to operate the crime prevention function. It is characterized by holding. Here, the security device is installed in a building structure equipped with a “security camera” 0102, a “locking device” 0103, etc. for taking a video of the security space, and information on the network with the locking device and other devices. May be configured to transmit and receive. In any case, by adopting a configuration having such a feature, it becomes possible to identify the facility exit who is in an important position from the viewpoint of crime prevention management.

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks of the security device according to the present embodiment. As shown in this figure, the “security device” 0200 of this embodiment includes a “control unit” 0201, a “security operation unit” 0202, an “operator shooting unit” 0203, a “record holding unit” 0204, Consists of

  Note that any of the functional blocks of the security device described below can be realized as hardware, software, or both hardware and software. If a computer is used, specific configurations include a CPU, main memory, GPU, image memory, graphic board, bus, or secondary storage device (hard disk, nonvolatile memory, CD, DVD, SD card, etc. Storage devices and reading drives for these media), cameras, sensors, input devices used for information input, scanner devices, printers, other hardware components such as external peripheral devices, and external peripheral devices thereof Examples include an interface, a communication interface, a driver program for controlling these hardware, and other application programs. Then, by the arithmetic processing of the CPU in accordance with the program developed on the main memory, the data input from the input device or other interface etc. and held in the memory or hardware is processed and accumulated, or each of the hardware And commands for controlling the software are generated. Here, the program may be realized as a plurality of modularized programs, or may be realized as a single program by combining two or more programs.

  Here, FIG. 14 is a schematic front view showing a display of a security device having a function for monitoring the achievement degree of the energy saving target and its peripheral surface as an example of the security device of the present embodiment. The security device shown in this figure displays on the “display” 1404 the setting of the energy saving target input by the operation of the “operation button” 1402, the status of the degree of achievement of the target, and the like. It is conceivable to take a picture with the “camera” 1405 and output the detection result when the occurrence of an abnormal state is detected by the “sensor” 1403 or the like. By adopting such a configuration with a function that enables monitoring of the degree of achievement of energy conservation targets while there are no people in the facility, waste of standby power required even when there are no people in the facility It becomes possible to strengthen the crime prevention system while checking.

  Further, the present invention can be realized not only as an apparatus but also as a method. A part of such an apparatus can be configured as software. Furthermore, a recording medium on which such software is recorded is naturally included in the technical scope of the present invention.

  Further, as shown in FIG. 3, the security device of the present invention is configured so as to be able to communicate with other electrical devices, smart meters, home gateways and other external devices, so-called BEMS (Building It is also possible to configure a part of various systems for energy management such as Energy Management System (FEMS), Factory Energy Management System (FEMS), and Home Energy Management System (HEMS). By adopting a configuration that makes it possible to manage the energy consumption and the crime prevention system in an integrated manner, it is possible to realize efficient facility management.

  The “security operation unit” 0202 has a function of operating a security function. The “crime prevention function” here refers to a series of functions for detecting the occurrence of an abnormal situation in the facility and outputting the detection result. The "output of detection results" includes transmission of detection signals to terminal devices (administrator terminals) managed by managers such as security companies, voice output, display output, print output, warning lamp output, etc. Each means is included, and these may be used alone or in combination.

  By the way, “facility” here refers not only to commercial facilities that are indoor spaces such as offices and stores, but also to educational facilities such as schools, hospitals, museums, museums, and a certain range such as stadiums, amusement parks, and parks. It also includes facilities that are limited outdoor spaces.

  As a specific function for detecting the occurrence of an abnormal situation, for example, it is conceivable to operate various sensors using infrared rays, light, ultrasonic waves, temperature, vibration, or the like. By adopting this method, it becomes possible to accurately grasp the occurrence of an abnormal situation such as the intrusion of a suspicious person into the facility, the dropping or throwing of a suspicious object, by the operation of the various sensors. Therefore, in the case of this example, “activate the crime prevention function” means that various contents are instructed to various sensors.

  The detection result may be output through an external peripheral device connected to a security device such as a display or a speaker, or may be output to a terminal device managed by a facility manager through a network. The security device uses these various means to output the detection results, making it possible for the facility manager to quickly grasp the fact that an abnormal situation has occurred, while on the other hand, the suspicious cause of the abnormal situation It is also possible for the person to recognize the fact of grasping by the facility manager, and as a result, it is possible to abandon the purpose of the facility intrusion.

  By the way, the non-normal acts that are subject to "crime prevention" here are not limited to criminal acts literally, but violate certain rules such as unethical acts, employment rules, and workplace rules. Actions involving emergencies such as actions can be widely covered.

  The “control unit” 0201 has a function of controlling the crime prevention operation unit. “Control” here refers to various instructions that can be given to the crime prevention operation unit from starting up, operating, and stopping various means for detecting the occurrence of an abnormal situation such as a sensor. It means that. Specific control contents include, for example, activation of a crime prevention operation unit, setting of a crime prevention space range to be a crime prevention target, a sensor for detecting occurrence of an abnormal situation, etc. Number of sensors, etc.), detection method of detection result of occurrence of abnormal situation (output of detection signal, audio output, etc.), output form (time for continuing output, output timing, etc.) and output It is possible to select the destination, detect it, output the detection result, stop the operation, etc.

  In addition, the environment for crime prevention can change at any time, as represented by changes in the facilities, changes in the busy season, changes in the management system, etc., so the contents to be controlled by the control unit can be changed as appropriate. It is desirable to be configured as follows.

  The “operator photographing unit” 0203 has a function of photographing an operator when an operation is performed on the control unit. In other words, “operation on the control unit” means any operation performed by the operator for the purpose of the operation of the crime prevention function, and the operation on the control unit functions as a trigger for the operator photographing. When a plurality of operations are performed on the control unit, the configuration may be such that the operator is photographed at each time point when all the operations are performed, or when the operations are continuously performed within a predetermined time. Alternatively, a configuration may be adopted in which shooting is performed only at one timing, and shooting is not performed at other timings.

  The “operator” here refers to a person who intends to control the crime prevention function, and if it is normal, the person who has such intention intends to operate the crime prevention function in the facility. Be the first to enter the room or stop the crime prevention function at the time of leaving or the next business start. In addition, an unauthorized intruder into the facility can be considered as a person who has the intention in an abnormal situation.

  Here, the timing of shooting may be the time when the operation to the control unit starts to be accepted, the time when the operation is completed, or any other timing at which the appearance of the operator can be accurately shot. It is possible. For example, it is assumed that a predetermined password is required in advance to perform an operation on the control unit, and photographing is performed at a timing when the input of the password is received by the operator. In this way, it is possible to further improve the effectiveness of operator shooting by defining a required operation procedure and adopting a configuration in which shooting is performed while the operation procedure is taken.

  Note that “photographing the operator” does not require capturing the specific appearance of the photographer and photographing the whole body. The photographer photographing unit only needs to be able to specify “who” is the operator, and any specific photographing means may be used as long as the request is satisfied. For example, it is conceivable to employ a method of photographing at least one judgment element for specifying the face, the name tag worn by the photographer, clothes, and other operators in addition to the whole body of the photographer. As a specific photographing method, for example, a photographing method using an infrared light may be adopted. By adopting such a photographing method, it is possible to photograph the appearance of the operator without being affected by the brightness in the facility and record who is the operator.

  The operator photographing unit is a function for photographing the operator to the last, and is not intended to photograph the crime prevention space. Therefore, in a specific security space, there may be a configuration in which one or a plurality of security cameras are provided separately from the security device of the present embodiment. In FIG. 1 already shown, an embodiment in which a “security camera” 0102 is provided separately from the “security device” 0101 as described above is shown.

  Furthermore, “photographing” here does not particularly distinguish between an image and a moving image, and includes capturing in any manner. Therefore, not only a mode for capturing only still images or only moving images, but also a mode for capturing images by combining images with, for example, relatively short time moving images, is included in the “shooting” here. By shooting the operator by combining images and videos in this way, it is possible to avoid situations where it is difficult to identify the subject to be shot due to blurring when recording only still images, and to identify who is the operator. It becomes possible to specify clearly.

  In addition, “photographing” here does not necessarily mean that direct photographing is performed within the security device. For example, the security device and the manager terminal are connected via a network, the operator's image information grasped by the crime prevention device is transmitted to the manager terminal, and a process for photographing the image information at the terminal is prompted. This is also included in “shooting” here (the same applies to the record holding unit described later). By adopting a configuration that can also be provided outside the crime prevention device with the function of actually taking a picture, it is possible to avoid the situation in which the photographed person erases or destroys the image information taken by destroying the crime prevention device. be able to.

  The “record holding unit” 0204 has a function of holding a record shot by the operator shooting unit. As “photographed recording”, for example, it is conceivable that the photographed image is in a file format such as an image file or a moving image file. Here, the file contains information such as the shooting date and time, the main events that occurred in the facility on that day (year-end party, no overtime day, △△ project deadline), and the details of the operation that the operator was performing at the time of shooting. Each may be linked and recorded. By adopting such a configuration, it is possible to check whether the operation date and time and the operation content by the operator are reasonable, that is, whether or not an inappropriate operation is performed in an unnatural time zone. Become.

  Since the record holding unit is a function related to holding extremely important information in order to make crime prevention effective, it must be handled with care. Therefore, when the record is held by the mechanism in the security device by the function, the security device is required to adopt a structure in which the record holding mechanism cannot be easily taken out from the outside. . Specifically, in addition to a physical structure that is shielded from other mechanisms, a shield structure may be employed to prevent intrusion from external communication means. By adopting this configuration, it is not possible to easily grasp the retained record from the outside, and it is possible to grasp the record only when it is necessary to grasp the record after an emergency, that is, an abnormal situation Become. By expecting such an effect, it is possible to suppress a situation where an image relating to the privacy of an operator or the like is unnecessarily disclosed to the outside.

  In addition, in the case of transmitting a signal indicating that an abnormal situation has been detected to the manager terminal, not only the signal but also a record photographed by the operator photographing unit may be transmitted together. Good. By adopting such a configuration, the person in charge of management who has received the detection signal can immediately identify the person who is thought to have left the facility last time. In addition, the required confirmation can be taken quickly, and the initial response when an abnormal situation is detected can be appropriately performed.

  Here, the security device of this embodiment may be provided so that it can be used in a building structure having a locking device at the entrance. As an example of “to be usable” here, there is a state in which the security device and the locking device can transmit / receive information to / from the network with both or other devices. Conceivable. At this time, for example, when the entrance / exit is opened / closed within a predetermined time when the start operation of the security device is performed, it is recognized that the operator of the security device has exited, the locking device is started, It is conceivable to adopt a configuration for performing a locking process. By adopting such a configuration, it becomes possible to grasp the operation procedure of each device that the operation of the locking device is performed after the operation to the security device, and the operator of the security device, that is, the security space concerned It becomes clearer that they are the last leavers.

<Specific configuration>
FIG. 4 is a schematic diagram illustrating an example of a configuration when each functional configuration of the security device of the present embodiment is realized as hardware. The operation of each hardware component will be described with reference to this figure.

  As shown in this figure, the security device includes “CPU” 0401, “storage device (storage medium)” 0402, “main memory” 0403, “output interface” 0404, An “input interface” 0414 is provided, and information is transmitted / received to / from external peripheral devices such as “camera” 0405, “display” 0406, “printer” 0407, and “administrator terminal” 0408 via an input / output interface. Do. The storage device stores various programs as described below, and the CPU reads these various programs into the work area of the main memory, and develops and executes them. Note that these components are connected to each other via a data communication path such as “system bus” 0409 to transmit / receive information and process information.

(Specific processing of the control unit)

<Process flow>
FIG. 5 is a diagram illustrating an example of a process flow of the security device according to the present embodiment. The flow of processing in the figure consists of the following steps. First, in step S0501, a process for determining whether or not an operation has been performed on the security device is performed. If it is determined that there is an operation, the process proceeds to step S0502. If it is determined that there is no operation, the process returns to step S0501 again. In step S0502, a process for photographing the operator is performed (operator photographing step). In step S0503, the image photographed in the operator photographing step is recorded (record holding step). In step S0504, the security function is operated according to the operation content determined to be received in step S0501 (security operation step). In FIG. 5, the security operation step process is shown as being performed after the record holding step. However, this is only an example, and the security operation step is processed at any stage after step S0501. May be.

<Effect>
According to the present invention having the above-described configuration, it becomes possible to identify a facility final exit person in an important position from the viewpoint of crime prevention management.

<< Embodiment 2 >>
<Overview>
The security device according to the present embodiment is basically the same as the security device according to the first embodiment, but has a function of recognizing a human face image and recognizes the operator's face image when the control operation is performed. An additional feature is to disable the operation when it is not possible. By having such a configuration, it is possible to prevent the “spoofing” of the operator by others, and to accurately and reliably grasp who is the operator of the crime prevention device that occupies an important position in crime prevention management in the facility. Become.

<Functional configuration>
FIG. 6 is a diagram illustrating an example of functional blocks of the security device according to the present embodiment. As shown in this figure, the “security device” 0600 of this embodiment includes a “control unit” 0601, a “security operation unit” 0602, an “operator photographing unit” 0603, a “record holding unit” 0604, "Face image recognition means" 0605. Since the basic configuration is the same as that of the crime prevention apparatus described with reference to FIG. 2 of the first embodiment, the function of the face image recognition means, which is a difference, will be described below.

  “Face image recognition means” 0605 has a function of identifying the face of the operator. “Identify the face” means, for example, storing position information of average coordinates where each part such as eyes, nose and chin constituting a human face is stored in advance and referring to the position information. A method of extracting a part that is considered to be a human face from the captured video and specifying a part corresponding to the face in the image is conceivable. As a specific identification method, a method of checking a photographed face image against a pre-registered face image database based on information such as the relative positions and sizes of the characteristic parts can be considered. In the face image database, staff face image data is registered together with the staff name, gender, department, job title, working years, staff ID, etc., and the captured face image is registered in the database. It may be possible to judge the consistency of.

  Here, as an example of a possible process, when it is determined that there is consistency, a process according to the operation content is performed by assuming that the operation by the operator is valid, and a face image that is not registered in the database If it is determined that, the operation by the operator is invalidated and no control is performed. In addition to not performing any control, it may be determined that an operation by a suspicious person has been performed, and an output process of the detection result may be performed assuming that an abnormal situation has occurred. At this time, the record holding unit of the security device of the present embodiment may be configured to record the staff ID together with a photographed image or the like. By adopting this configuration, for example, it is possible to eliminate the “spoofing” that conceals the fact that you operated the security device by wearing only uniforms and name tags of other facility staff and photographing only the name tag etc. become.

  Note that the face identification algorithm is not limited to the geometric method described above. For example, information on general human face images and individual face images is statistically digitized and stored as a template. In addition, a method of comparing a photographed face image with a digitized image may be used, and other specific algorithms are not excluded.

<Specific configuration>
Since the hardware configuration of the security device of the present embodiment is basically the same as the hardware configuration of the security device of the first embodiment described with reference to FIG. 4, a face image that has not been described so far will be described below. A specific process of the recognition unit will be described.

(Specific processing of face image recognition means)
When receiving a signal that the control program should be executed, the CPU executes a “face image recognition program” to perform processing for recognizing the operator's face, and stores the processing result at a predetermined address in the main memory. Then, the CPU performs a process of executing the operation content only when the processing result can recognize the face image.

<Process flow>
FIG. 7 is a diagram illustrating an example of a process flow of the security device according to the present embodiment. The flow of processing in the figure includes the following steps. First, in step S0701, a process is performed to determine whether any operation has been performed on the security device. If it is determined that there is an operation, the process proceeds to step S0702. If it is determined that there is no operation, the process returns to step S0701 again. In step S0702, a process for photographing the operator is performed (operator photographing step), and the process proceeds to step S0703. In step S0703, the image photographed in the operator photographing step is recorded (record holding step). Thereafter, in step S0704, processing is performed to determine whether the image captured in the operator imaging step can be recognized as a face image (face image recognition step). If the determination result indicates that the recognition is not possible, the process returns to step S0701. If the determination result indicates that the recognition is not possible, the process proceeds to step S0705. In step S0705, the security function is activated in accordance with the operation content that has been accepted (security operation step). In FIG. 7, the record holding step is shown as a process before the face image recognition step. However, this is only an example, and the record holding step is processed at any stage after the operator photographing step. May be.

<Effect>
In addition to the effects described in the first embodiment, the security device according to the present embodiment makes it possible to accurately and reliably grasp who is the operator of the security device that occupies an important position in crime prevention management in the facility. .

Since the basic configuration is the same as that of the crime prevention apparatus described with reference to FIG. 2 of the first embodiment, the activation means which is a difference will be described below.

  The “activation means” has a function for activating the crime prevention operation unit. As described above, the operator photographing unit has a function of photographing the operator when an operation is performed on the control unit. In the security device of this embodiment, since the control unit has an activation means, when an operation is performed on the control unit for the purpose of activating the crime prevention operation unit, the operator imaging unit can shoot the operator. Will be done. Since the security device is normally activated when the last person remaining in the facility exits, the person who left the facility last can be clearly identified by providing a configuration to capture the person. It becomes possible to specify.

<Specific configuration>
The hardware configuration of the security device of this embodiment is basically the same as the hardware configuration of the security device of Embodiment 1 described with reference to FIG. Therefore, in the following, a specific process of the activation unit that has not been described so far will be described.

When the CPU receives an input of a signal indicating that the security function should be activated, the CPU executes the “activation program” and performs a process to execute the security operation program.

<Specific processing>
FIG. 9 is a diagram illustrating an example of a process flow of the security device according to the present embodiment. The flow of processing in the figure includes the following steps. First, in step S0901, a process is performed to determine whether or not there has been an operation for prompting the crime prevention apparatus to activate the crime prevention function. If it is determined that there is an operation, the process proceeds to step S0902. If it is determined that there is no operation, the process returns to step S0901 again. In step S0902, a process for photographing the operator is performed (operator photographing step). In step S0903, the image photographed in the operator photographing step is recorded (record holding step). On the other hand, in step S0904, a security function is activated in accordance with the operation content that has been accepted (security operation activation step). In FIG. 9, the record holding step is shown as a process before the crime prevention operation starting step, but this is only an example, and the record holding step is processed at any stage after the operator photographing step. May be.

<< Embodiment 4 >>
<Overview>
The security device of this embodiment is basically the same as the security device described in any one of Embodiments 1 to 3, but is characterized in that it further has a function of photographing a security space. By providing this configuration as a feature, it is possible to check the state of the crime prevention space with a video even when the crime prevention device is not operated after the crime prevention function is activated.

<Functional configuration>
FIG. 10 is a diagram illustrating an example of functional blocks of the security device according to the present embodiment. As shown in this figure, the “security device” 1000 of the present embodiment includes a “control unit” 1001, a “security operation unit” 1002, an “operator photographing unit” 1003, a “record holding unit” 1004, A “photographing unit” 1005. Since the basic configuration is the same as that of the security device described with reference to FIG. 2 of the first embodiment, the imaging unit which is a difference will be described below.

  The “shooting unit” 1005 has a function of shooting the crime prevention space. The “crime prevention space” here is a concept including any space expected as an operation target of the crime prevention apparatus, and it is not particularly limited whether it is an indoor space or an outdoor space. The specific shooting method is the same as that already described in the description of the operator shooting unit, and the type of still image or moving image is not limited. It should be noted that the recording taken by the photographing unit may be held by the record holding unit.

  Note that “photographing a crime prevention space” refers to photographing a specific space that is positioned as the crime prevention target, and is distinguished from the function of the operator photographing unit having a function of photographing only the operator. The However, a configuration in which the operator photographing unit also has the functions of the photographing unit, that is, a configuration in which the functions of both units can be realized by one functional block may be adopted. By adopting such a configuration, it is possible to simplify the structure of the entire crime prevention device.

Therefore, in the following, specific processing of the photographing unit that has not been described so far will be described.

(Specific processing of the shooting unit)
The CPU reads information obtained by executing the control program, executes a “photographing program”, and performs processing for photographing the security space. Then, information obtained as a result of photographing is stored at a predetermined address in the main memory.

<Process flow>
FIG. 11 is a diagram illustrating an example of a processing flow of the security device according to the present embodiment. The flow of processing in the figure consists of the following steps. First, in step S1101, a process is performed to determine whether any operation has been performed on the security device. If it is determined that there is an operation, the process proceeds to step S1102. If it is determined that there is no operation, the process returns to step S1101 again. In step S1102, processing for photographing the operator is performed (operator photographing step). In step S1103, the image photographed in the operator photographing step is recorded (record holding step). On the other hand, in step S1104, the security space is photographed in accordance with the contents of the operation that received the input (photographing step). In FIG. 11, the record holding step is shown as a process before the photographing step, but this is only an example, and the recording holding step is processed at any stage as long as it is after the operator photographing step. Also good.

<Effect>
In addition to the effects described in the first embodiment, the crime prevention device having the above-described configuration can confirm the state of the crime prevention space with a video even when the crime prevention device is not operated after the crime prevention function is activated. Is possible.

<< Embodiment 5 >>
<Overview>
The crime prevention device of this embodiment is basically the same as the crime prevention device having the functions described in any of the third and fourth embodiments, but controls the shooting function according to the passage of time from the start of shooting. It is a feature. By providing this configuration as a feature, it is possible to check the state of the facility from when the security function is activated until when the operator leaves.

<Functional configuration>
FIG. 12 is a diagram illustrating an example of functional blocks of the security device according to the present embodiment. As shown in this figure, the “security device” 1200 of the present embodiment includes a “control unit” 1201, a “crime prevention operation unit” 1202, an “operator photographing unit” 1203, a “record holding unit” 1204, It has “activation means” 1205, “elapsed time control means” 1206, and “imaging unit” 1207. Since the basic configuration is the same as that of the crime prevention device described with reference to FIG. 2 of the first embodiment, the elapsed time control means, which is a difference, will be described below.

  “Elapsed time control means” 1206 is a function for controlling the photographing unit according to the passage of time from the start of photographing when the photographing of the crime prevention space by the crime prevention operation unit is started by operating the starting means of the control unit. Have “Controlling the photographing unit according to the passage of time from the start of photographing” can be considered to control the time and timing of photographing, for example, continuing photographing for a predetermined time after starting photographing (for example, one frame) It is conceivable to control the image capturing unit at a timing such as not performing image capturing until an abnormal state is detected by various sensors after that. When shooting a movie at the shooting unit, you will be continuously shooting movies during the crime prevention operation. In such cases, even if the normal state continues for a long time, you should shoot movies continuously during that time. As a result, energy such as electric power required for photographing was wasted. However, by adopting such a configuration, it becomes possible to perform pinpoint shooting focused on only when the crime prevention function is activated and when an abnormal situation is detected, so that the crime prevention purpose can be realized with energy saving.

<Specific configuration>
The hardware configuration of the security device of this embodiment is basically the same as the hardware configuration of the security device of Embodiment 1 described with reference to FIG. Therefore, in the following, specific processing of the elapsed time control means not described so far will be described.

(Specific processing of elapsed time control means)
The CPU executes a shooting program and also executes an “elapsed time control program”, and performs a process of controlling the shooting program so as to perform shooting according to the passage of time since the start of shooting.

<Process flow>
FIG. 13 is a diagram illustrating an example of a processing flow of the security device according to the present embodiment. The flow of processing in the figure consists of the following steps. First, in step S1301, a process is performed to determine whether or not there has been an operation with a content that prompts the security device to activate the security function. If it is determined that there is an operation, the process proceeds to step S1302, and if it is determined that there is no operation, the process returns to step S1301 again. In step S1302, processing for photographing the operator is performed (operator photographing step). In step S1303, the image photographed in the operator photographing step is recorded (record holding step). On the other hand, in step S1304, shooting is performed at a predetermined time and timing corresponding to the passage of time from the start of shooting (elapsed time shooting step). In FIG. 13, the record holding step is shown as a process before the elapsed time shooting step, but this is only an example, and the record holding step is processed at any stage after the operator shooting step. May be.
